A first side of the body is connected to the first electronic module. A second side is connected to the second electronic module and located on a different side from the first side. The distance between the second side and the second electronic module is shorter than the distance between the second side and the first electronic module.

The second buffer element transmits the electronic signal from the second side to the first side, wherein the transmission directions of the electronic signals transmitted by the first buffer element and the second buffer element are opposite.

A fixed wireless access network provides for high-frequency data links between aggregation nodes and endpoint nodes. The system further provides for lower frequency wireless data links, which have carrier frequencies less than high-frequency wireless data links. These lower frequency links provide for auxiliary communications between the aggregation nodes and one or more endpoint nodes. During normal operation, the nodes exchange packet data via the high-frequency data links. However, when impairment of the high-frequency data links is detected, the nodes direct the packet data over the low-frequency data links instead until the high-frequency data links are no longer impaired.

Each of the packet structures of the plurality of packet structures can include a single destination address configured to identify which of the plurality of peripheral devices will receive peripheral device data from the host computing device in the present packet structure and which of the plurality of computer peripheral devices will not receive peripheral device data from the host computing device in a present packet structure; and a data field configured to contain peripheral operational data for each of the plurality of peripheral devices.

In some embodiments a transceiver is configured to wirelessly transfer data between a host computing device and one or more peripheral devices over a communication path using a communication data construct comprising a packet structure arranged in a repetitive communication structure. The repetitive communication structure can include a transmit time window within which the host transmits data to the one or more connected peripheral devices and a receive time window within which the host receives data from the one or more connected peripheral devices. A duration of the receive time window is set based on a predetermined communication report rate between the host computing device and the one or more connected peripheral devices. A new peripheral device is added as a connected peripheral device when the new peripheral device transmits a request to the host to be added as a connected peripheral device and the receive time window has time available to add the new peripheral device.
